Overview & Reviews

Coming off a redesign last year, the 2008 GMC Sierra 1500 has only minor changes this year. Satellite radio is now standard equipment and an integrated trailer brake controller is optional. GMC says it will also be offering 22-inch wheels (as a dealer accessory) and a flashier version of the Z71 Off-Road package called the Sierra All Terrain.

• Refined and very quiet ride, pleasing fit and finish inside, seats are comfortable for long drives, comprehensive list of safety equipment.

• Larger turning circle than most rivals, mediocre interior storage and cupholders.

  Great truck at a great price - 2008 GMC Sierra 1500
  By OleMissDispatcher - October 29 - 11:53 pm

  Have owned truck for almost 600 miles and really enjoy the truck. It has 5.3 V8 with the Flex Fuel Management. City driving is ok, highway is a lot better. For a base model, it came fully loaded with all power options, CD, cruise, fog lights, chrome bumpers, towing package, XM, and OnStar (which I think XM and OnStar were standard). Truck can ride rough over unkept streets, but still a lot better than my old Chevrolet Tracker. Air and heat are great. Cant wait to try the 4x4!

  08 SLT Crew Z 71 pack - 2008 GMC Sierra 1500
  By L. Morris - October 19 - 3:06 pm

  Last truck was a 96 Z71 ext cab Chevy. This truck is awesome! I love 99% of it! I chose this, over the somewhat cheaper Silverado, due to the way the dealer treated me and the price they quoted me. No one else could come close to my deal.

  What a difference! - 2008 GMC Sierra 1500
  By Sierra - August 28 - 8:43 am

  Immediately drove 2 WD truck (17" tires) to central OH from central FL - 20.2 mpg @ cruise set mostly 75 mph. Returned to FL w/bass boat in tow 15-17 mpg. Ride is super w/effortless handling. Plenty of power with 5.3 engine. I wanted a truck with car type ride. Thats why I got 2 WD with 17" rims.

  I love this truck - 2008 GMC Sierra 1500
  By R Taylor - July 31 - 5:06 pm

  I decided to buy a new truck and chose the new body GMC for several reasons. The overall design is great! The interior is nicer than ever and everything is within easy reach. The big bold grille stands out in a crowd.

  Better then the rest - 2008 GMC Sierra 1500
  By blksiryder - May 10 - 3:30 am

  I just got my new GMC with the 5.3. I love the fact of the fuel managment system. The mpgs could be better but not bad. The engine is a power house. I traded my 2000 turbo diesel for this truck and with the 100k powertrain warranty. I know it will last the the term of the loan. I would buy 2 if I needed them.

  Best One Yet - 2008 GMC Sierra 1500
  By Best One Yet - May 2 - 12:46 pm

  After driving GMC trucks since 1974 this new 2008 Sierra is the best one yet. The interior is outstanding with great back support in the bucket seats; easy accesss to everything on the dash; to great controls on the steering whell. This is the first time for GMC to have cruise control on the steering wheel and it is much easier to operate. Performance is outstanding with the 5.3 engine and my gas mileage is good as well. With the 4-6-8 engine I get 24 to 25 mile to the gallon at 55 mph. Amazing! My friends drive Fords and Dodges and their milage is so bad 10-12 mile per gallon. Too bad they didnt buy a GMC. My company truck is a Ford 4x4 and on a good day it gets 12-13. Really sad.

  Overall a great truck - 2008 GMC Sierra 1500
  By EddieH - April 14 - 11:16 pm

  Overall I love this truck. I LOVE the styling, and its very comfortable to drive. There are a few nitpicking things though, I hate the hesitation when you give it gas suddenly. I am told this is due to GM using "torque management" in their PCM tune. Ford and Dodge do not this. This is probably the only real disappointment. The others are small things like when you hit the recirculation button on the AC, then turn the AC on, it defaults back to outside air, you have to hit the recirculation button again. Drives me nuts. The mileage is about what you would expect from a truck this size and engine size. Overall, I love the truck..the quality is very good.

  08 Sierra Denali - 2008 GMC Sierra 1500
  By Jeff B. - March 21 - 5:50 pm

  This 1/2 ton is awsome. 403 HP All wheel drive makes this a blast to drive. very comfortable. pulls my 24ft enclosed trailer and 26ft camp trailer pretty decent. 15-17 mpg not too bad for 400 hp. stabillatrack and speed sensitive steering make this truck handle very well. I had a 400+hp 2005 Duramax crewcab that I loved and traded it for this. I realy love this truck!

  08 Sierra 1500 - 2008 GMC Sierra 1500
  By blurry25 - April 30 - 3:46 am

  Coming from a Honda Civic the Sierra 1500 feels like a monster. What a dream to drive. I actually enjoy driving to work now. One of the first things I noticed was how quiet the ride is. With the windows up road noise is virtually none existent. Ive been getting around 16.6mpg with all around driving. I suspect that will go up as the motor breaks in, but hey if youre looking for fuel economy buy a prius and just hope that someone in a 1500 doesnt hit you. I highly recommend getting the remote start option. I always start the truck a few minutes before I leave and it either turns on the heater or AC depending on the inside temp of the truck. Nothing like hoping into the perfect climate.
